Hi, I would like to buy a surge protector to protect my iMac, MacBook, and MyBook. I only need a 3 socket protector - I really don't need, or want, anymore than 4. The reason I would like a Belkin is that it is a big name, they are reasonably priced, and they offer a nice lot of damage protection (would they pay out though, that's the question?). Which one would you recommend, preferably for < £20? Thanks, Virtual.
